INTRODUCTION

This technical manual covers the operational and service instructions for the wind drift determination parachute, further referred as the “spotter parachute”. The wind drift determination parachute is a weighted, glide free, wind drift parachute designed for use by military personnel to aid in the pre-determined spot to release parachutist. The alternate orange and white gores will assist with good visual contact throughout the flight pattern. The spotter parachute consists of three major components; the canopy, the deployment bag with static line attached and the weight. The canopy is a 12-foot pound canopy with twelve 8.5-foot suspension lines all attached to a single connector link. The deployment bag with static line attached houses the parachute and weight and provides a means of automatic opening and deployment for the canopy. The weight is attached to the suspension lines by means of the single connector link and is variable from approximately 17 pounds base to 22 pounds with all additional weights installed.

SECTION II DESCRIPTION

2-1 The spotter parachute assembly part # AMTC-K1075 consists of the components listed in figure 2-4. 2-2 Canopy part # AMTC-S1242 is a round parachute constructed of MIL-C-7020D, Type I fabric. The canopy is composed of 12 MIL-C-5040, Type IIA suspension lines with core lines removed. Each suspension line is attached to the skirt hem and terminates at a single connector link (MS22021). Standard retainer bands (NSN: 1670-00-568-0323) are used to stow lines and static line. See figure 2-1.

2-3 The deployment bag with static line part # AMTC-C1100-DA is constructed to enclose the packed parachute and weight. One end includes an elastic (bungee) cord installed in the mouth of the bag to retain the weight from exiting until being deployed from the aircraft. The static line attached to the opposite end of the opening is constructed of type XII MIL-W-4088 nylon webbing and is approximately 14 feet 6 inches in length. See figure 2-2. 2-4 The weight part # AMTC-M2046-17 is attached to the single connector link and assists the rate of descent of the canopy. The base weight is approximately 17 pounds with eye bolt (see figure 2-3) and has 2 two pound and 1 one pound additional weights to increase the rate of descent as desired. The additional weights are identified in figure 2-4 for further reference.

SECTION III OPERATION

3-1 The spotter parachute is recommended for use in training and operational jumps by military personnel using standard round parachute systems, generally at low altitudes. Aircraft type should be the same as the intended aircraft for live jump operations and aircraft speed should not exceed live jump speeds. The spotter parachute should be dropped from the same relative altitude and airspeed that the jumps will be conducted. The weight below the canopy stabilizes the canopy and controls the weight of descent. Under average conditions the spotter parachute with minimum weight will descent and drift in a manner that will compare to a man and equipment total weight of 170-230 pounds. Maximum weight (22 pounds) will compare to a man and equipment total weight of approximately 300 pounds. 17 lb weight will produce a rate of descent of approx. 15-18 FPS, whereas 22 pounds will produce a ROD of approx. 17-20 FPS.

SECTION IV PREPARATION FOR USE

4-1 Place the canopy on the packing table with the identification panel facing up. Install suspension lines in proper sequence on the single connector link. Insert the other half of the connector link into the base weight assembly.

Figure 4-1 Attach Link to Weight Figure 4-2 Place cap on link

4-2 Replace the cap of the connector link and tighten the screw to the full seated position. Torque the screw to 20-25 inch pounds. NOTE: The serrated part of the screw should automatically move to the locked position. If plate does not move, back off screw and press the plate to closed position and retighten. 4-3 If using spotter parachute for water operations, refer to section 7 for further information on attaching flotation.

SECTION V

INSPECTION AND REPAIR

5-1 Only personnel qualified to pack parachutes should perform inspection, repacking and maintenance of the assembly. 5-2 PREFLIGHT INSPECTION: Observe condition of all visible components. Ensure deployment bag and static line are free of broken threads, cuts frayed areas or other damage. Inspect snap hook for rust, corrosion, freedom of operation and proper attachment. Inspect elastic cord for proper installation, deterioration and over all usability. If additional weights are installed, inspect for tightness of bolt and ensure weights are free of dings, burrs that could cut components in which they might come in contact with. If flotation is installed, ensure the flotation system is installed properly in elastic retainers and speedlink is tight. 5-3 COMPLETE INSPECTION consists of unpacking and stretching the canopy out on the packing table. Canopy should be shaken out of all debris. Inspect suspension line continuity and over all condition of the parachute in accordance with applicable personnel manuals (MC-1B, MC-1C,….) Limit repairs to what is allowed for personnel parachute systems. Inspect deployment bag and static line completely inside and out for broken stitching, holes, cuts and small tears. All small repairs should be done in the loft. Inspect snap hook for rust, corrosion, freedom of operation and proper attachment. Inspect complete weight assembly for burrs and/or damaged areas. Check threads of weight and eye bolt for damage. Replace if damage is found. Ensure allen screws on top of weight are tight.

Cg5� � � � � � � � � � � � � � � � � Complete inspection should be done every 360 days or earlier if applicable. 5-4 SALT WATER IMMERSION - If parachute is exposed to salt water for less than 3 days (72 hours) immediately rinse the parachute assembly in fresh water. Canopy should be washed a minimum of three separate times. The canopy should then be suspended to dry in a drying tower for at least 48 hours or longer to ensure canopy is thoroughly dry. Suspension lines should be untangled allowing for an equal suspended weight on the canopy.

Fresh water immersion is harmless if clean, but canopy should be washed in accordance with section 5-4 above. This should be done incase there are unknown chemicals in the fresh water. 5-5 STORAGE – Parachute assembly should be stored in a clean room, away from direct sunlight. Also should be kept on a shelf to avoid moisture or dirt, which may be on a floor.

SECTION VI PACKING

6-1 PACKING should be completed by qualified individuals and in a clean environment.. Qualified individual is one who has had formal instruction on parachute packing and maintenance. All tools should be accounted for before and after the packing is complete. A missing tool or not following the instructions may lead to a malfunction of the system. 6-2 LAYOUT - The layout of the canopy consists of placing the apex to the top of the table and attach the connector link to a board or the weight for the system can be used as long as the weight does not roll. There should be 6 gores to the right and 6 to the left. NOTE: Ensure that canopy is not inverted and suspension lines have good continuity.
